Re: The history of stdint.h ?

Thanks! I do have a puzzle for you: I've been comparing several
OS's and find they are remarkably different WRT stdint.h.

Depending on the OS, the appearance and content of stdint.h vary for
compatibility reasons.

The features provided by stdint.h -- stuff like int8_t, int16_t, etc. --
were always needed. Unfortunately, there was no one way to providing it
-- some folks used #ifdef checks on compilers/OSes/architectures, others
used autoconf, etc.

Which standard the "std" in "stdint.h" respresents is up for
considerable debate. I'm most familiar with what C99 requires; others
have mentioned the Single Unix Specification. But until these see more
widespread adoption, all you can depend upon is it being the standard
for release X of OS Y on architecture Z -- which might even mean it
doesn't exist at all (e.g., FreeBSD 4.8).
